. table and Fat Cutting Machines, of which the following is a specification. v

Our invention is designed to produce a simple and efiicient apparatus by which meats, vegetables, &c., can be cut rapidly into small pieces and is embodied in the various novel combinations of elements hereinafter described, and pointed out in the claims.

To illustrate our invention, we annex hereto two sheets of drawings, in which the same reference characters are used to designate identical parts in all of the figures, of which-- Figure 1 is a top plan view of the apparatus. Fig. 2 is a central vertical longitudinal section. Figs. 3 and 4 are end elevations.

Fig. 5-is a detail view. on an enlarged scale, in

detail in section on the line B B of Fig. 5, but

with the rotating knife omitted. Fig. 8 is a similar fragmentary view on the line C C of ends with-the sleeves 14 and 15. These elon gated sleeves 14 and 15 have secured therein the bearing-rods 16 and 17, and these bearingrods have secured .on the outer ends thereof the sleeves 18 and 19, which are formed on the arms of the casting 20, whose function is to support the chopping-block 2 1, which, as seen in Fig. 6, has its face covered by a series of intersecting channels 22 of the proper size to accommodate the intersecting knives 23, which are, broadly speaking, carried by the annulus 24, which in turn is supported by its elongated sleeves 25 and 26, which are adapted to slide back and forth onthe bearing-rods 17 and 16, respectively. The sleeve 13 has secured therein the nut 27, in which is screwed the shaft 28, which rotates in the elongated bearing 29', formed in the yoke-shaped cross piece 30 ofthe casting, making up the annulus 2 4 and the sleeves 25 and 26. This shaft 28 has its bearingv portion cooperating with the bearing-sleeve 29, somewhat-reduced in cross-section, as shown,'and is provided with the'collars 31 and 32, which serve to hold it from longitudinal movement in the bearing, the collar 32 preferably beingprovidedwith a semicircular annular ball-race which is mounted'a series of antifriction-balls-33-, co-

operating with a corresponding channel formed'in the collar 34:, secured to the end of the sleeve 29, so as to reduce the friction of the shaft as it rotates in thebearing-sleeve 29.- Where the mechanism thusfar described is preferably of 1 sheet metal and corresponds in size and shape to the "block 21, overwhich itslides, it being supported from the annulus- 24, as by screws 35 passing-through the flanges 35", as seen in Fig. 2. It will be apparent that with the parts inthe position shown in Fig. 2 if any material to be cut up isplaced in the casing'35 andthe shaft 28 is turned the'casing will be forced over the block 21 and the knives 23 will be forced outwardand finally into the'channelsin the face of the block, so that any material will neces-' mechanism thus far describedwe employ-the rotating knife 36, which is carried by the :eccentric arm 37, supported on the-end of the shaft 28 and adjacent to the knives, 23, so that it will shear against the backsthereof;

As the shearing-knife cannot rotate atthe-axis of the shaft, to prevent any clogging at that point We preferably fill the central recess between the kniveswith thepointed deflecting piece or spike 38 and ofcourse provide :3)

similarly-shaped recess 39in-the face of the block,21, which the spike enters when the knives are forced into the block.

To convenientlysupply the material to the apparatus, we referably secure the bracket- 40 on the top 0 the standard and lace therea knives are drawn out and the casing is ready to be filled. To facilitate filling the casing,

we preferably provide it with a pair of doors 42, hinged at 43, so that they can be thrown wide open, so that the material can be dropped into the casing from the hopper.

To supply the necessary power to the shaft 28, we preferably secure upon it the gearwheel 44, which meshes with an elongated driving pinion 45, which is conveniently mounted upon the extended end of the rod 17 and which is provided with a preferably removable handle 46, by which the pinion is turned. The pinion is held from longitudinal movement on the rod 17 by reason of the screw 47 entering into the annular channel 48, formed in the end of the rod 17. When the knives have been forced home and it is desired to recharge the device, the crankhandle 46 is removed, and by turning the gear-wheel 44 by means of the knob or handle 49, with which it is provided, the apparatus can be opened very much more rapidly than it was closed.

In forming the dividing apertures by means of the knives 23 we employ a novel constructi on. These knives, as is best seen in Figs. 7 to 9, consist of thin blades, the front edges of those running in one direction having the recesses 50 therein of the width of the blades,

vided with recesses on one side to accommodate the ends 53 of the blades running in one direction, while it will be provided on its other side with the necessary recesses to accommodate the ends 54 of the blades running in the other direction. We are not of course 111 the employment of our invention limited to any particular shape of casing, as we may employ a s uare one, as indicated in Fig. 10, instead of %he circular one shown in the other views.

While we have shown and. described our invention as embodied in the form which is at resent considered best adapted to carry out its purposes, it will be understood that it is capable of some modifications and that we do not desire to be limited in the interpretation of the following claims, except as may be necessitated by the state of the prior art.
